Polymerisable compositions.

摘要

A polymerisable composition comprising an ethylenically unsaturated urethane composition comprising at least one ethylenically unsaturated urethane compound having an average double bond functionality of greater than 1.0, an ethylenically unsaturated monomer which is a vehicle for, and is copolymerisable with, the unsaturated urethane composition, and a particulate methyl methacrylate/butadiene/styrene (MBS) rubber modifier. Also claimed is a polymer article prepared from said composition and a method of preparing said article.
